The object of my invention is the vproduction ofran all steel car roof'of minimum weight and thickness which shalll be water tight, which shallwithstand the wear and tear of service, and which shall be easilyrepaired or renewed. v

and wooden side and endsheathin'g 3, 41,'and comprises metal roof sheetssuppo'rted on anall steel substructure. f This substructure consists ofchannel carlines 5 which'extend from side plate to side plate and arev:securely bolted thereto at their ends 6,.':which areseti bent downoutside of the. sidel 'plates'.jf-The i carlines are arranged lwiththeir websfilp; permost, andghavelateral base flangesTpar-' allellto the'websl and extending'. otward along the -lower 'extremities oaf 4the:side

flanges or walls., 'To 'the base flanges aref` I Secured" metal' PUIHHS8 extending length;A

wise of thefcar, and which -may'be continu'- 4ons from' end to end ofthe car.l At the center-line 'ofthe cara yinetal ridge piece 9," of isubstantially the `same cross-section as the carlines, is arrangedlengthwisev of the carl` upon the topv webs of' the carlines with itsbase flanges 10 in contact therewith and secured thereto.- The purlinsare flanged up between the ca-rlines, and the tops ofthe flanges supportsheet-metal `roof 'sheets 11 out of Contact with the base flanges of thecarlines. The roof sheets extend from eaves to ridge of the car and havetheir side and ridge margins 12 and13 turned upwardly and their .eavesmargins 14 trirned downwardly." They are arranged upon the tops of thepurlins and base flanges of the ridgepiece with their uptnrned side andridge -margins adjacent to the sides of the carlines and ridge piecerespectively, and with their .downturned eaves margins overhanging thefasciae l5 atthe eaves of the car. The lcorners where theupturned'inargins of each roof sheet come together are vformed solid,and the extremities of these upturned margins, except at the corners,are rebent dinally upon the tops of the carlines/ and ridge4 piecerespectively, with the ridge seam covegs ,covering the inner ends of theside fsea'm covers'.A `The seam covers-.project on each side of theridge -piede and carhnes to cover the adjacent uptiirhed flanges oftheroof sheets, and the lateral flanges 22 and 23` ofthe seam covers restfiat o-n the roof Vsheets between their .upturned flanges and sheets,and will pass along the space between these'fianges' and the seam coversand off` the eaves,

,The\side seam` covers are secured at the r'eaves' by" means of eavescaps,` 24 riveted` thereto andv bolted t0 the fascine and side'vplates-below the eaves; These eaves caps .have projections 25=on` theirunder4 sides 'which vrest on top of the fascine to insure that the eavescaps shall be 4'properly spaced above the4 fasci to avoid vpinching thecorners of the roof sheets,` which are turned down fbetween the eaveskcaps and fascia. Holes 26- are left'inl the walls of the" eaves 'capsbelow thel eaves to allow water running down'between the marginalflanges of' the roof sheets and seam covers to pass off the eaves, andtoprevent cinders-from collecting in the s ace between the' eaves capsand fascia. lips 27' bearing lightly on the roof sheets areu'sed tosecure the latter atl the l eaves between the eaves caps. Ridge cornercaps l28 of'sheet metal, shaped to conform to the side seam covers andridge seam covers lat their intersection, are fitted over the ridge andvside seam covers at the ridge corners of the sheets and serve to securethe latter. at jthe ridge. j The side seam covers stop short 'of theridge marginal flanges on the roof sheets.- The ridge seam covers arecut away at the sides where Vtheir flanges approach the side marginalflange of the roof sheets, and the tops of the yri ge seam-covers. are

' extendedat the ends to meet'at about above the center. lines of thecarlines. The ex'- tended vends of the ridge' seam covers andl the ridgecorner caps have alining holes 29 punched through them and throughV thetop -web of the ridge piece through which pass bolts 30 4which secure`the wooden lrunning board saddles 31, supported crosswise upon' theridge piece over the carlines. The ends ofthe running board saddles reston the side seam covers above the earlines, and are partly supportedthereby.y Metal platesv32 :are placed over the running board` saddlesLiscate to prevent water from passing throughthe bolt holes and into thecar, and upon these plates the running boards 33 are arranged and'secured to the saddles by nails or other suitable fastening means.` 'l

The modifiedforms of roof sheet andA seam cover shownin Figs. 10 to 13,inclusive, are

particularly well suited for meeting the requirements of hard service.The roof sheets eaves flanges 39. The roof sheets are dished betweentheirside flanges, that is, the portions 40 of the sheets adjacent tothe side flanges are inclined upwardly to where they join the bases ofthe side flanges. The seam covers il have downwardly and outwardlyinelined'sides' 42, as in the form shown in Figs. l to 9, and areprovided with lateral base flanges 43 conforming tothe slant of themarginal portions l0 of the roof sheets. The lateral base flanges 43 ofthe seam covvers'press. down on the slant-ing marginal portions 40 ofthereof sheets between the corrugations and side flanges of the roofsheets, and form substantially water tight resilient joints. Spacing theslanting marginal or dished portions ofthe roofsheets above thesubstructure eliminates any trouble due to the seam covers pinching theroof sheets down on the substructure -and preventing the slightshifting, of the roof sheets to accommodate themselves to distortion ofthe substructure. There is sufficientj'spring in the seam cover flangesand in the upwardly inclined marginal portions of' the roofl sheets tokeep them in close contact at all times, and to maintain the tightnessof the joint even though the roof sheets may become displaced from theirnormal po sitions. Moreover, the pressure ofthe seam covers on theinclined marginal portions of they sheets has a tendency to maintain thesheets in their normal positions. This shape and arrangement of seamcovers and roof sheets not only provides a' water tight seam or jointbetween adjacent roof sheets well adapted to prevent the entering ofwater into the car, and one in which water and cinders will not collect,but also vprovidesa flexible means for retaining the sheets in normalposition on the car.

The eaves ends le ofthe side seam covers are turned' down over theeaves, covering the ends of the carlines and the eaves corners of theroof sheets, and are spaced away from the fascine sufliciently to allowslight freedom of movement of the corners of the roof' sheets crosswi'seof the roof. The

IllA

Lineare ldownturned vends of the seam covers are loosely secured to theside of. the car by bolts 45 which also attach the fasciae to the i 47and fascia for the purpose of spacing the .side plates.l The bolts 45pass through holes 1n the ends of the seam covers larger than the bolts,and bushings `46 are placed on the Y ends of the bolts between-thefastening nuts saddles and running boards my roof is .made entirely ofmetal, preferably steel,

forming a light, stiff, water tight structure of shallow depth, in whichall parts are readily inspected and easy to remove and eavescaps andclips and yet are not rigidly replace Without dismantling the entireroof. The roof sheets are veryl securely held in place by the' ridge andseain covers and secured to the substructure, and may be removed andlreplaced `without difiiculty by removing theadjacent ridge and seamcovers and eaves caps and clips. The thickness of the-ioni sheetsy andspacing of the pu'rlin's.

with respect to the ridge piece and side plates are such that the sheetswill support the ,weight of a man without deflecting unduly, and thus nowooden roof sheathing need be used, either to support the roof sheets asin the outside metal roof, or to protect them as in the inside metalroof, as made heretofore.
